How can I find the inverse of a Ricker wavelet

I want to find the inverse of a Ricker wavelet.

I have generated the wavelet using the following code

    function y=wavelet(dt,nt,f,delay)
    t=(0:(nt-1))*dt;
    t=t-delay;
    tmp=pi*pi*f*f;
    t2=t.*t;
    y=(1-2*tmp*t2).*exp(-tmp*t2);
    end

I tried to use fft and reciprocate the function (i.e.1/Wavelet) and return it back in time by ifft but I face the problem of dividing by zero. I looked into many ways to regularize it but it doesn't seem to give me a good result.

What is the best way to find the inverse wavelet.

I appreciate your help

Thanks
